CROSS REFERENCE TO RELATED APPLICATION

The present application claims priority from U.S. Provisional Patent Application No. 61/814,374 filed on Apr. 22, 2013, which is incorporated herein by reference in its entirety.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The invention relates to wall mounted toilets and, in particular, to a carrier or a support system for adequately supporting a toilet and the weight of the user, and for placing the toilet in fluid communication with a waste fitting.

2. Description of Related Art

Typical closet carrier systems and fittings are designed for mounting and supporting water closets that include a flush valve or flush tank that flushes the water closet with a volume of 1.5 gallons per flush or greater and for placing such water closets in fluid communication with a waste fitting. Accordingly, such typical systems have been designed to accommodate a large volume of flushed fluid. However, recently, flush valves and tanks are being developed to utilize much less water volume per flush in order to conserve water and may now utilize as little as 1.28 gallons per flush. The carrier systems are not configured to accommodate such a low flush volume and cannot adequately flush material down the drain lines.

An example of a closet carrier of the type discussed above is disclosed in U.S. Pat. No. 8,141,177, issued on Mar. 27, 2012, which is assigned to Zurn Industries, LLC, the assignee of the present application, and is incorporated herein by reference in its entirety. The adjustable coupling, faceplate, fitting, and other components of the carrier(s) disclosed therein are configured, both in terms of size and general shape, to convey flush water and waste from a water closet to a waste line at a volume of 1.5 gallons per flush or greater. When such carriers are used in conjunction with a water closet utilizing a low amount of water per flush, the flush water and waste is conveyed more slowly and inefficiently through the coupling and the fitting, resulting in water and waste becoming retained or trapped within the coupling or fitting and leading to clogs within the system.

SUMMARY OF THE INVENTION

Accordingly, there is a general need in the art for a water closet carrier system that is configured to mount and support a water closet on a wall, and accommodate flush volumes as little as 1.28 gallons per flush in order to adequately convey flushed fluid from the water closet to a horizontal fitting.

According to an embodiment of the present invention, a closet carrier system is configured to provide optimized flow and evacuate waste more efficiently downstream from the toilet to the fitting by increasing flow velocity through the carrier system and is substantially lighter in weight as compared to prior art carrier systems.

According to another embodiment of the present invention, a closet carrier system includes a unique faceplate, waste fitting, and feet, and is configured to more efficiently convey waste fluid from a water closet having a flush tank or valve that flushes at 1.28 gallons per flush. In other words, the closet carrier system is configured to transmit waste fluid down the line further when used in connection with a water closet having a flush tank or valve that flushes with a volume of 1.28 gallons per flush. To that end, certain components of the system, such as the adjustable coupling and the sweep passageway in the waste fitting, are specifically designed to optimize flow and to evacuate the waste more efficiently and get it down the line further.

Further, the closet carrier system will be configured such that the components of the system, as well as the entire system itself, are smaller, lighter, and easier to move around a job site. As a result, installation of the closet carrier system will be easier and reduce the likelihood of worker fatigue, lifting injuries, etc.

According to a particular embodiment of the present invention, a closet carrier for a water closet is provided. The closet carrier includes a faceplate having a first side and a second side, an adjustable coupling connected to and extending from the first side of the faceplate, the adjustable coupling being configured to be connected to the water closet and placed in fluid communication therewith, at least two vertical supports adjustably connected to the first side of the faceplate for supporting the system on a floor surface, and a fitting connected to the second side of the faceplate. The fitting includes an endplate, an inlet defined within the endplate, an intermediate portion, and a main body defining a main passageway of the fitting. The fitting is connected to the second side of the faceplate by the endplate, such that the inlet of the fitting is in fluid communication with the adjustable coupling. The main passageway of the fitting is placed in fluid communication with the inlet by the intermediate portion of the fitting. The intermediate portion of the fitting is configured to accelerate a velocity of a flow of waste fluid from the inlet of the fitting to the main passageway.

According to another particular embodiment of the present invention, a method of conveying waste fluid from a water closet to a fluid waste system is provided. The method includes providing a closet carrier that includes a faceplate having a first side and a second side, an adjustable coupling connected to and extending from the first side of the faceplate, the adjustable coupling being configured to be connected to the water closet and placed in fluid communication therewith, at least two vertical supports adjustably connected to the first side of the faceplate for supporting the system on a floor surface, and a fitting connected to the second side of the faceplate. The fitting includes an endplate, an inlet defined within the endplate, an intermediate portion, and a main body defining a main passageway of the fitting. The fitting is connected to the second side of the faceplate by the endplate, such that the inlet of the fitting is in fluid communication with the adjustable coupling. The main passageway of the fitting is placed in fluid communication with the inlet by the intermediate portion of the fitting. The method further includes transmitting waste fluid to the intermediate portion of the fitting through the adjustable coupling and the inlet of the fitting, and accelerating a velocity of a flow of the waste fluid to the main passageway of the fitting within the intermediate portion of the fitting.

According to yet another embodiment of the present invention, an arrangement of closet carriers is provided. The arrangement includes at least two closet carriers, each closet carrier including a faceplate having a first side and a second side, a coupling connected to and extending from the first side of the faceplate, the coupling being configured to be connected to the water closet and placed in fluid communication therewith, at least two vertical supports adjustably connected to the first side of the faceplate for supporting the system on a floor surface, and a fitting connected to the second side of the faceplate. The arrangement further includes at least two strut members, each of the at least two strut members being connected to a respective one of the at least two closet carriers, and a carrier member connected to all of the at least two strut members.

DETAILED DESCRIPTION OF THE INVENTION

For purposes of the description hereinafter, spatial orientation terms, if used, shall relate to the referenced embodiment as it is oriented in the accompanying drawing figures or otherwise described in the following detailed description. However, it is to be understood that the embodiments described hereinafter may assume many alternative variations and embodiments. It is also to be understood that the specific devices illustrated in the accompanying drawing figures and described herein are simply exemplary and should not be considered as limiting.

With reference to FIGS. 1-9, a closet carrier 10 is shown in accordance with an embodiment of the present invention. The closet carrier system 10 is configured to be connected to a water closet or toilet (not shown) in order to mount and support the water closet on the wall of a structure, and to place the water closet or toilet in fluid communication with a fluid waste system.

As shown in FIGS. 1-9, the closet carrier system 10 includes a faceplate 11 having a first side 12 facing upstream with respect to the flow of waste fluid through the system 10 and a second side 13 facing downstream. The faceplate 11 includes an internally-threaded horn 17 extending from the first side 12 of the faceplate 11. The horn 17 is provided for connecting an adjustable coupling 30 to the faceplate 11, such that the coupling 30 extends from the first side 12 of the faceplate 11. The horn 17 surrounds an opening extending through the faceplate 11 from the first side 12 to the second side 13. The adjustable coupling 30 has a hollow cylindrical body that defines an internal passage 33 having an internal diameter ID. The adjustable coupling 30 includes closet gasket 31 that is configured to form a tight fluid connection between the adjustable coupling 30 and a discharge port (not shown) of the water closet so that the adjustable coupling 30 is placed in fluid communication with the water closet, and waste fluid released from the water closet when the water closet is flushed is conveyed into the internal passage 33 of the coupling 30. The adjustable coupling 30 also includes a threaded exterior surface 32 for adjustably connecting the coupling 30 to the horn 17 of the faceplate 11. The horn 17 may include a notch (not shown) defined therein that receives an O-ring (not shown) to seal the engagement between the adjustable coupling 30 and the horn 17. The adjustable coupling 30 may further include a knockout diaphragm 30A provided within the internal passage 33. The knockout diaphragm 30A allows for pressure testing of the carrier assembly 10 during installation. After the carrier assembly 10 is assembled and pressure tested, the knockout diaphragm 30A may be dislodged from the internal passage 33 of the adjustable coupling 30 and removed.

The faceplate 11 includes at least two threaded holes 14 that are provided for connecting a support arrangement, such as horizontally-extending threaded rods or carriage bolts (not shown), to the faceplate 11. The support arrangement serves to structurally connect the water closet to the faceplate 11 such that the closet carrier system 10 is able to support the weight of the water closet and the user on the structure.

The closet carrier system 10 also includes at least two vertical supports 20 provided on each of the lateral sides of the faceplate 11. Each vertical support 20 includes a foot 21 configured to engage the floor of the structure, wherein the water closet is mounted such that the at least two vertical supports 20 support the weight of the water closet on the floor of the structure. Each foot 21 includes a U-shaped notch 22 defined therein to allow a fastener (not shown) to be passed through the foot 21 in order to fasten the vertical support 20 to the floor of the structure and secure the vertical support 20 in place on the floor. Each of the at least two vertical supports 20 also includes a vertical elongated slot 23, which is provided for receiving fasteners (not shown) to connect the vertical support 20 to the first side 12 of the faceplate 11. The fasteners extend through the elongated slot 23 and engage holes 15 defined in the faceplate 11 in order to adjustably connect the faceplate 11 to the vertical support 20. In this manner, the vertical position of the faceplate 11 with respect to the floor of the structure may be adjusted during installation of the system 10. According to one embodiment, each of the vertical supports 20 may be symmetric in shape with a foot 21 provided at each end of the vertical support 20 such that the vertical support 20 is reversible and may be connected to either one of the right and left sides of the faceplate 11.

The carrier system 10 further includes a waste fitting 40 connected to the second side 13 of the faceplate 11. The waste fitting 40 includes an endplate 41, an inlet 43 defined within the endplate 41, an intermediate portion, and a main body 46 defining a main passageway of the fitting 40. The waste fitting 40 is connected to the second side 13 of the faceplate 11 by way of the endplate 41 that includes holes 42 defined therein for receiving fasteners (not shown) that connect the endplate 41 to the faceplate 11. The faceplate 11 includes vertical elongated slots 16 that receive the fasteners to connect the waste fitting 40 to the faceplate 11, such that the vertical position of the waste fitting 40 with respect to the floor and the faceplate 11 may be adjusted during installation of the system 10. As shown in FIGS. 6-9, the endplate 41 of the fitting 40 is connected to the second side 13 of the faceplate 11, such that the inlet 43 is in fluid communication with the internal passage 33 of the adjustable coupling 30. The inlet 43 of the fitting 40 may have an oblong circular shape having a width or diameter approximately equal to the inner diameter ID of the internal passage 33 of the adjustable coupling 30. The adjustable coupling 30 may be connected to the horn 17 of the faceplate 11 so as to extend through the faceplate 11 and be in direct fluid communication with the inlet 43 of the fitting 40. A gasket (not shown) may be provided between the endplate 41 and the second side 13 of the faceplate 11 in a position surrounding the inlet 43 to seal the engagement between the faceplate 11 and the endplate 41 of the fitting 40. The gasket may be shaped in a corresponding manner to the endplate 41 and may further include holes for the fasteners connecting the faceplate 11 and the endplate 41 to ensure proper alignment of the gasket with the inlet 43 and the adjustable coupling 30.

The waste fitting 40 also includes an oblong circular plenum chamber or bubble 44 at the upstream end thereof on which the endplate 41 is disposed. The interior of the bubble 44 is in fluid communication with the internal passage 33 of the adjustable coupling 30 via the inlet 43 defined in the endplate 41. The waste fitting 40 further includes a sweep passageway 45 extending at an angle from the bubble 44. The sweep passageway 45 is in fluid communication with the interior of the bubble 44 and the main passageway defined in the main body 46 of the fitting 40. The bubble 44 and the sweep passageway 45 of the fitting 40, in combination, form an intermediate portion of the fitting 40 by which the main passageway of the fitting is placed in fluid communication with the inlet 43 of the fitting 40. The main passageway of the fitting 40, in turn, is configured to be connected with the fluid waste system of the building so as to convey fluid waste from the fitting 40 to the fluid waste system. Accordingly, waste fluid flushed from the water closet is conveyed from the water closet through the internal passage 33 of the adjustable coupling 30 and into the bubble 44 of the waste fitting 40 via the oblong circular-shaped inlet 43. The waste fluid then passes from the bubble 44 through the sweep passageway 45 into the main passageway defined in the main body 46 of the fitting 40 where it is then conveyed into the building's fluid waste system in a manner well known to those having ordinary skill in the art. The waste fitting 40 may further include an anchor support 47 disposed on the main body 46 for connecting the waste fitting 40 to an anchor bar or similar support (not shown) fastened to the floor of the structure in order to anchor the waste fitting 40 to the floor of the structure against the weight of the water closet and a user.

The adjustable coupling 30, the horn 17 of the faceplate 11, and the fitting 40, in particular the bubble 44 and the sweep passageway 45 of the fitting 40, are configured for accommodating a lower flush volume than typical for standard closet carrier systems and specifically to accommodate a flow volume of approximately 1.28 gallons per flush from the water closet. Accordingly, the internal passage 33 of the adjustable coupling 30 has a reduced internal diameter ID that is optimized for encouraging increased flow velocity of the waste fluid through the coupling 30 and evacuating waste through the system 10 such that the flow of waste fluid through the coupling 30 is more efficient. The bubble 44 and the sweep passageway 45 of the waste fitting 40 are similarly optimized such that a smaller volume of waste fluid, specifically 1.28 gallons per flush, can be efficiently and completely conveyed from the water closet to the main passageway defined by the main body 46 of the fitting 40.

More specifically, to achieve more efficient flow of waste fluid through the system 10, the intermediate portion of the fitting 40, in particular the sweep passageway 45, is configured to accelerate the velocity of the flow of waste fluid from the inlet 43 to the main passageway defined in the main body 46 of the fitting 40. The effect of accelerating the flow of waste fluid through the sweep passageway 45 is achieved by configuring the sweep passageway 45 to decrease in size between the bubble 44 and the main passageway defined in the main body 46 of the fitting 40. Decreasing the size of the sweep passageway 45 accelerates the flow of waste fluid through the fitting 40 by converting the pressure of the flow into kinetic energy in a manner similar to the effect of a nozzle on a flow of fluid therethrough. To that end, the sweep passageway 45 is provided with an optimized shape and dimensions to achieve acceleration of the flow of waste fluid to a highest practical velocity for the fitting 40 so that the flow of waste fluid through the fitting 40 is efficiently conveyed to the fluid waste system of the building.

Typically, when a water closet is flushed to dispose of a waste fluid consisting of a mixture of flush water and other liquids and solid and semi-solid materials, the pressure of the flow volume of the waste fluid, typically 1.5-1.6 gallons per flush, is sufficient to carry the entirety of the waste fluid from the water closet through the carrier system to the fluid waste system of the building. For newer water closets designed to utilize a low volume of water per flush, for instance 1.28 gallons per flush, the pressure of the flow of waste fluid from the water closet may be insufficient to carry all of the solid and semi-solid material forming part of the waste fluid from the water closet to the fluid waste system of the building and the solid and semi-solid materials will become stuck and accumulate within the coupling or the fitting of the carrier, resulting in clogs within the carrier system. The adjustable coupling 30 and the fitting 40, in particular the sweep passageway 45 of the fitting 40, of the closet carrier 10 according to the invention are configured to optimize the flow of waste fluid through the closet carrier 10. The sweep passageway 45 is specifically configured to accelerate the flow of waste fluid through the fitting 40 in order to impart greater kinetic energy to the flow of waste fluid through the closet carrier 10 and thereby carry the solid and semi-solid materials forming part of the waste fluid farther through the closet carrier 10 and break up the solid and semi-solid materials for more efficient conveyance with the liquid portions of the waste fluid.

With reference to FIG. 7, the sweep passageway 45 is at least partially defined by a first internal sidewall 45A substantially extending at a first acute angle A with respect to a plane defined by the endplate 41 of the fitting 40 and a second internal sidewall 45B substantially extending at a second acute angle B with respect to the plane defined by the endplate 41 of the fitting 40. The first acute angle A is greater than the second acute angle B such that the second internal sidewall 45B converges toward the first internal sidewall 45A as the first and second internal sidewalls 45A, 45B extend from the bubble 44 to the main passageway defined in the main body 46. It is to be appreciated that the first and second internal sidewalls 45A, 45B may have slight curvature at a radius significantly larger than their length. Accordingly, the sidewalls 45A, 45B will extend roughly along a tangent extending at the respective angles A, B with respect to the plane defined by the endplate 41 of the fitting 40. It is also to be appreciated that the sweep passageway 45 may also extend from the bubble 44 along a downward angle to the main passageway. According to one embodiment of the invention, the first acute angle A is greater than 30° and the second acute angle B is less than 25°. According to another embodiment of the invention, the first acute angle A is approximately 35.5° and the second acute angle B is approximately 23°. According to yet another embodiment of the invention, a difference between the first acute angle A and the second acute angle B is greater than 10°.

With further reference to FIG. 7, the sweep passageway 45 has a maximum width X between the first internal sidewall 45A and the second internal sidewall 45B at a point within the sweep passageway 45 proximate to the bubble 44, and a minimum width Y between the first internal sidewall 45A and the second internal sidewall 45B at a point within the sweep passageway 45 proximate to the main passageway defined in the main body 46. The maximum width X of the sweep passageway 45 is approximately equal to the inner diameter ID of the internal passage 33 of the adjustable coupling 30, and the minimum width Y of the sweep passageway 45 is less than the maximum width X of the sweep passageway 45 and the internal diameter ID of the adjustable coupling 30. According to one embodiment of the invention, the internal diameter ID of the adjustable coupling 30 and the maximum width X of the sweep passageway 45 are less than or equal to 4 inches and are greater than 2.75 inches, and the minimum width Y of the sweep passageway 45 is greater than or equal to 2.125 inches and less than 2.75 inches. According to another embodiment of the invention, the internal diameter ID of the adjustable coupling 30 and the maximum width X of the sweep passageway 45 are approximately 3 inches, and the minimum width Y of the sweep passageway 45 is approximately 2.25 inches.

It is to be appreciated that the specific dimensions ID, A, B, X, Y described above may be varied within ranges deemed to be suitable by one having ordinary skill in the art to achieve the effect of accelerating the flow of waste fluid through the fitting 40, and efficiently conveying waste fluid through the system 10 to the fluid waste system of the building.

With reference to FIGS. 1-9, a method of conveying waste fluid from a water closet to a fluid waste system includes providing the above-described closet carrier 10 having the faceplate 11, the adjustable coupling 30, the at least two vertical supports 20, and the fitting 40. The method further includes transmitting waste fluid to the intermediate portion of the fitting 40 through the adjustable coupling 30 and the inlet 43 of the fitting 40 and accelerating a velocity of a flow of the waste fluid to the main passageway defined in the main body 46 of the fitting 40 within the intermediate portion of the fitting 40.

With reference to FIGS. 10 and 11, according to another embodiment of the invention, multiple closet carriers 10 of the type discussed above may be assembled into an arrangement of closet carriers for purposes of pre-fabrication of the carriers 10 away from the installation site, and subsequent common transportation and installation of the carriers 10 at the job site. As shown in FIG. 11, the arrangement includes at least two and particularly three closet carriers 10, each of which includes a faceplate 11, a coupling 30, at least two vertical supports 20, and a fitting 40, as described above with reference to FIGS. 1-9. As shown in FIGS. 10 and 11, the arrangement further includes at least two strut members 50, each of which is connected to a respective closet carrier 10. In particular, the arrangement includes at least four strut members 50, each strut member 50 being connected to a respective vertical support 20 of the closet carrier 10. The strut members 50 are, in turn, connected to a carrier member 52 such that the closet carriers 10 are mutually connected to the carrier member 52 for common transportation and installation of the closet carriers 10. To that end, each of the strut members 50 includes a slot or hole 51 formed in the upper and lower ends of the strut member 50. The slots or holes 51 in the ends of the strut member 50 are configured to receive fasteners (not shown) that connect the strut member 50 to the carrier member 52 and to the adjoining end of the respective vertical support 20 by also engaging the notch 22 in the end of the vertical support 20. In this manner, the closet carriers 10 may be pre-fabricated away from the installation site by assembling each carrier 10 and then arranging the carriers 10 in a bank for common transportation and installation at the installation site by connecting the carriers 10 to the carrier member 52. Each of the carriers 10 within the bank may also be pre-adjusted to a desired height, for instance a set height along a fall line for aiding the transmission waste fluid through multiple carriers 10 to the fluid waste system of the building, in a manner well known to those having ordinary skill in the art.

While specific embodiments of the invention have been described in detail, it will be appreciated by those having ordinary skill in the art that various modifications and alternatives to those details could be developed in light of the overall teachings of the disclosure.
